Sir, Thank you for your interest in our products. The dash hawk requires that pins 6 and 14 are populated in your vehicles OBD-II connector. You may want to take a look and check that out first. http://dashhawk.com/faq.html There is also a list of vehicles that the dash hawk should work with. http://dashhawk.com/support.html If pins 6 and 14 aren't populated, the dash hawk will not work. Generally the dash hawk only works with 2004 and newer vehicles. Thanks, MSD tech
